Member 21 is attachedto the table It surrounding the heating member and spaced therefrom. Theroller 26 is journaled in cover member 21. The cover member 21 isprovided with a slot 28 in the side thereof opposite the open side ofthe channel-shaped upper portion 2! of the heat transfer member. Theslot 28 is used for threading the tape through the heat transfer unit. Aroller 29 is journaled in the upper end of tubular cover 2! to guide thetape as the tape leaves the top of the heat transfer member. As shown inFigs. 2 and 4, the tape makes a quarter turn inside the heat transfermember and leaves the heat transfer member and the tubular cover thereofclosely spaced from presser foot I! so that, once the tape is heated bypassing above heating element 14, the tape is maintained hot by the heattransfer member and reaches presser foot ll in heated condition.

As shown in Figs. 1 and 2, the machine is provided with a cover member3| which is hinged to an auxiliary tape receptacle 32. The coverincludes an inverted channel-shaped portion 33 which fits over theflanges of the tape guiding channel In as shown most clearly in Fig. 5.The flanges of cover portion 33 are spaced from the flanges of guide [8to provide an insulating air space therebetween. In addition, aninsulating pad 34 of asbestos or the like is attached to the web ofcover 33 as shown in Fig. 5, to insulate the cover.

my Patent No. 2,261,127.

When auxiliary tape receptacle 32 is in use, an idle roll 34 may beattached to cover 3| for guiding tape from the auxiliary roll into thespace above heating element 14. The roll 34 may be removed when tape isfed from below the table 16 from the roll 13.

The heating element 14 may be provided with a rheostat 36 as indicatedin Fig. 1, by means of which the heating element may be adjusted. Inaddition, appropriate thermostatic controls, not shown, may beincorporated in the heating element for controlling the heat thereof.

The tape heater, described above and illustrated in the drawing, issubject to structural modification without departing from the spirit andscope of the appended claims.

Having described my invention, what I claim as new and desire to secureby Letters Patent l. A tape heater for a machine for dispensingthermally responsive tape of the thermoplastic and pressure sensitivetype, which comprises an elongated hollow, substantially horizontal tapeguide, a flat elongated heating element in the lower portion of the tapeguide, a heat transfer member of heat conductive material attached tothe heating element at one end of the guide and extending upwardlytherefrom to the foot of a tape applying machine, said heat transfermember comprising a substantially horizontal bottom portion'of U-shapein section embracing the heating element to be heated vbythe same, anupper portion of upright, channelshape spaced above the bottom portionand facing away from the tape guide and an intermediate plate portionconnecting the bottom and upper portions guide, means for guiding at oneside of the tape guide, and means for guiding the tape through the tapeguide and. up between the fianges of the channel of the heat transfermember and spaced from the web and flanges thereof for heating the tapeas the tape is delivered to the tape applying machine.

2. A tape heater for a machine for dispensing thermally responsive tapeof the thermoplastic and pressure sensitive type which comprises anelongated hollow, substantially horizontal tape guide, a flat elongatedheating element in the lower portion of the tape guide, a heat transfermember of heat conductive material attached to the heating element atsaid end of the guide and extending upwardly therefrom to the foot of atape applying machine, said heat transfer member comprising a bottomportion embracing the heating element, an upper portion of uprightchannel shape spaced above the bottom portion and facing away from thetape guide, and an intermediate portion connecting the bottom and theupper portions at one side of the tape guide, and means for guiding thetape through the tape guide and up through the channel of the heattransfer member for heating the tape as the tape is delivered to thetape applying machine, said guiding means comprising a roller journaledadjacent the lower end of the upper portion of the heat transfer member.

3. A tape heater for a machine for dispensing thermally responsive tapeof the thermoplastic and pressure sensitive type which comprises anelongated hollow, substantially horizontal tape guide, a flat elongatedheating element in the lower portion of the tape guide, a heat transfermember of heat conductive material attached to the heating element atsaid end of the guide and extending upwardly therefrom to the foot of atape applying machine, said heat transfer member comprising a bottomportion embracing the heating element, an upper portion of uprightchannel shape spaced above the bottom portion and an intermediateportion connecting the bottom and upper portions at one side of the tapethe tape through the tape guide and up through the channel of the heattransfer member for heating the tape as the tape is delivered to thetape applying machine, and a hollow, protective cover surrounding theheat transfer member, said cover being provided with a slot extendingthe length thereof opposite the open side of the channel for threadingthe upper portion of the heat transfer memher.

4. For use with a stitching machine a tape magazine and guide comprisingmeans for holding a spool of tape, said tape having one of its facescoated with a thermoplastic adhesive, an elongated tape heating tunneloven, a chimney extending upward from one end thereof, an aperture inthe floor of said oven adjacent the end thereof spaced from saidchimney, heat producing means disposed on and substantially covering thefloor of said tunnel oven, said heat producing means being spaced belowand extending across the mouth of said chimney to a point adjacent saidaperture in the oven floor, a tape supporting guide roll adjacent saidaperture, a tape hold-down guide roll adjacent the base of said chimneyand spaced above. said heat producing means, a tape supporting guideroll adjacent the top of said chimney, said aperture and guide rollsbeing adapted to co-operate with a tape as described to substantiallylimit such a tape to a predetermined path through said oven and-chimney,a heat conducting member provided with a substantially tubular portionadapted to receive and engage the portion of said heat producing meansdisposed adjacent the chimney end of said oven, said member extendinginto said chimney and having a channel-shaped portion thereof on oneface of said tape may be rendered sticky by heating said tape and may bedelivered hot from the chimney mouth without said sticky face contactingany other surface while sticky.

5. A device according to claim 4 characterized by he fact that saidtunnel oven is provided tape passes and that in said chimney a. secondslot is provided joining said first slot and said open tunnel oven endand in registry with the channel in said heat conducting member wherebythreading of tape through said guide and heating means is facilitated.
